Referringto Figs. 1v and 2, the serving machine is shown comprisingthe outer casing 1, of suitable exterior contour, and formedof suitable material for heat-insulating the interior of the vcasino'. The cas,

ing 1 is `provided with suitable feet 2.

'lhe serving machine is provided with a suitable number of containers andmof suitable configuration determined 'by the particular use, and in the specific. embodiment shown there are four-containers 3, 4, 5, 6, having substantiallycylindrical inner and outer configurations and somewhat flared outwardly at its. upper end 7, see Figz'l. Theiower end of each container is provided with a suitable discharge opening 8, sec Figz; f im i The containers are mounted on Lthe table 9 shown as rotatably mounted within and disposed adjacent the bottom 10 of the 'casing 1. The table 9 is'provided with an upwa-rdly extending,centrally fixed rod 11', see Fig. 2, projecting through the top 12 of the casing and provided with thehandeholdy 13, to `afford manual operation of the table eXteriorly of the casingv 1. The table 9 is also provided with suitable 'locking means,

such las comprisingthelocking pin 14,V see F ig. Y`1, adapted to `be 'received within/the opening. 15, in the flange 16 of the tablev 9;

said pin 14, is mounted onthe'arm 17, `fined toatherod 18 projecting upwardly through thecasingil` and y'having vthe vknob 19 disposed above the top 12 of .the casingl for nranual operation exteriorly of the casing.'

The rod'18 is normally tensioned by the eX- pansive spring 20, shown coiled about the rod 18,having its "lower-end engagingthe inne;l face of the' bottom 10 of the casing and its upper end abutting the stop pin 21 ln `vthe particular forni of the inifention shown in thev drawing, the 'machine is especially adapted for' serving butter, for

vwhich vpurpose the lcontainersr may `be of cylindrical contour .and provided `with, a square. discharge opening 9.,` for the service of the usual square patties of butter. Such containers 3, 4, 5, 6 are conveniently arranged at1substanti'ally. quadrantv positions,

and accordingly the locking recesses 15 are four in number and may be disposed sub stantially inlradial alignment with the cen` ters of the respective containers. j #Thecasing 1 isprovided with a hinged cover 22,-having4 the knob 23, and suitably hinged to the fixed portion of the top 12 to vaiford 'charging the `foodstuff in bulk into e the container within access of the opening ,of the cover-,orffor removal or replaceloch ment. `Such arrangement affords charging cooling medium. The particular contour of each of the four refrigerating 'compartments may be varied, as will be understood, and in the particular form shown in the drawings, see Fig. 2, the contour conforms to the shape of the containers, the shape of the supporting table 9 and to provide a centra-l clearance through which extends the operating rodr11. f The cooling :compartments 25 `are also preferably' of suitable form at their inward,`.manually engaging facesto be self-locking in position about the containers. l

Preferably, seeFigs. `Z3 and 4each container 3 isremovably positioned yin the table 9, for which purpose the table 9 is provided with the perforation 26 adapted to'rcceive the protruding end 27 'of the container 3 snugly fitting the face of the perforation 26; Adjacent the protrudingl end 27, each" container 8 may also be provided with the-lateral flange 28 'constructed to firmly seat and retain the container Aon the table 9. 'The flange 28 is preferably provided ywith a recess 29 for receiving a locking pin 30 adjustably tapped, as by threading 31, in the table 9 and provided withajhead 32 adapted tofrictionally lock the lcontainer 3, shown in locking,position`in'.Fig.v 3. Upon rotat- .ingithe head 32 throng-ha half-turn, the head 32 is brought into register with the recess 29, enabling the container 3 to be raised from its seated position the table 9..

At suitable location on the casing 1 is arranged the operating mechanismof" the plunger for Aprojecting ythe butterl through the dischargeopening of the container, and in Vthe particular form of the invention shown in. the drawings, l have mountedy the. operating mechanism of the plnnger on the top 12 of the casingl,

The plunger, as shown in Figs. 1,5 and 6,

conforms to the inner contour of any container 3, and in this instance, is circular, in cross section. Preferably, the plunger 40 comprises an upperplate 41 having the boss 42 provided with the retaining plate 43 :having 'the' elongated slot or recess 44 of -suitable contour for freely receiving the foot 4o, see Figzd, of the plunger rod 46.` The 1 plungerj49is provided with the packing 47 positioned on theplate 49 by means of the retaining plate 49 heldin position bythe ing ypin 50 and nuti.)

ing 101, of the angled plate 91.

As appears from Fig. 13,.,the lateral con-k tour or' the mounting block .96 relative to the .lateral contour .of therecess 94 provides for the oppositely disposed clearances102', 102, toiaiford limited rotational movement 'or the bloclr 96 on its studs 98, 100, retarded 'endfoi the pawl toward its set of ratchet The centering block isprovided with suitable means iiorrestraining the plunger rod 46 from upward movement, upon the upward oscillation .of the pawls 65, 66, see g Fig. 1, comprising the holding'pin'106n0rmally held by. the spring 107 in engagement with aratclietftooth.- rl"he spring 107. is loosely mounted on the centering 'block 5 5, and is 'provided with the manipulating iin,-

. ger 108'adapted to be manually pressed'to i withdraw the positioning .pin 106, when it cillation of thejrespective levers-78, thereby actuating v each pawl 65, v66, downwardly' is desired to manually withdraw upwardly the plunger rod 46. In such manualjwithidrawal of theplungerrod 46, the tips of. the-respective pawls 65, 66, as well vas the finger 108 of the retaining spring 107',

' are pressed inl opposed o directions, "whereupon the .rod-,46 is free lto be slid manually 1 through its centering 'block 55. f 1 Upon downward oscillation ofthe operat# ing handle 67, and therewith downward oswhile in engagement .with their respective ratchet teeth 61, .62, the plunger rod; 46 is correspondingly forced dovvnwardly and, kthe plunger 40 correspondingly advanced inthecontainer 3 `to projectthe butteror other suitable lioodstufli through its discharge opening 8, preparatory to the operation or' the severing means.

is shownmounted at its upper end on the arcuate plate110, suitably mounted on the shaft 68 to provide' for the operation of the i link 109 during the final stage of downward eti movement or the operating handle 67. Such arrangement comprises, 1n the specic form illustrated, the arcuate plate .110 looselyv mounted on the` shaft `68, pin 111 fixed to the bearing 70,v or other ixed support `(see Fig. V2) and projecting into the short slot'r 112 of the arcuate plate 110, see Fig. 16; the plate 113 also loosely mounted on the vshaft G8, and provided with the long slot i 115fsai'd plate being provided with a registering long slot :115k and al pin 116- project- 4ing thc iinal downward Suitably connected toy l `the shaft 68 is provided a linlr109` for operating the-severing means under control of the operating handle 67. yThe Vlink 109.

ing through both slots 114, 114 and iXedly `carried bythe immediate disk 71 (see Fig. 1).k ,In Fig. 16, these parts are shown in their initial position, i..v e., when the operating handle is in its'upper position. During the initial strokeV of the handle, to effect the `aiilvance of vthe. plungenthepin 116 moved from its position lshown in full .lines `in Fig. 6 toits position at the opposite end of the slot 115, during which movement the plates 110, 113 'are idle. Upon continued movement of the handle and therewith the shaft 68, and thedislrs v71 and .pin 116, the ,pin 116 encounters the end of the `'slotl l115 thereby rotating the plate v110 until the pin 1.11 abuts the end 'of its slot 112, bringing the plate 110to rest, andthcreby deterniiin lmovement .of the handle 67. Y

As appears. in Figs. 14and '15, the linlr 109 is connected to one arm 120 of the bell crank 121, pivotally mounted at 122 on. the

casing 1 ot the nua-chine.v The other arm 123 ofthe bell crank lever 121 is connecte-d by the linlry124to theupper arm 125 of 90 the bell cranlr lever 126, pivotally mounted y and projecting through the recess extending through the bottom 10 rofthe casing 1, its lower arm V 127 being lconnected with` the spring frameh 128 (see F ig.f2) provided with v95 the positioning lugs 129 for receiving-'the' respective ends ot the severing wire 130, or equivalentlrnifelor other suitable".` severing means.'l f l Thus, upon operation of the lhandle 67 Iand oscillation of. theishatt 68m the direction or the arrow 83, see Fig. 16, during the linalextentfoix its downward movement, de-` termined by the" pin '111 and its slot 112, thelinlr 109 is actuated downwardly in' the 105 direction ofthe arrov.T 133;(see also Fig. 14),

rthereby rotating' thebell cranlr 121 in the severed by the vsevered means from the bulk of the' foodstuff, although, it will be understood, that the vsevering mechanisml is constructed to be arranged without such regulater. Thus, I in the specic embodiment shown, upon yclamping or otherwise fixing the plate `110 to plate 113, as by means oitx4 the pin V extending through an' opening 141 in the plate 110 and through theregisytering opening 142 in the plate 113, `or the equivalent, by forming the plate 110 inte- 130 needles n 5 grally with the platefll, as will be understood..l I i i For adjustable regulation, the plate 110 and the plate 113, as indicated "inF igs. 16, 17 and 1S, areseparateplates and adjustably connected to one another, as by providing ftheA plate 113 witha plurality of openings142 143, 144,.arranged similar to' the opening 141 on an are the center yof which `is coincident .with the center of; the

shaft 68, thereby enabling thepin 140, posi.- tioned ,in the opening 1.41 in the plate` 110 to be extended into any one of the register-` ing openings 142,143, 144, etc.,` to determine the eflective strolreof oscillation of the `pawlv advancing mechanism, kand .therebyfdetermine the amount of butter or `food` stuff advanced through the'dischargeopen-` ing.,v f Q t F or serving yforbutter or similar 'food-` stuf, the regulatingopenings 141, 142, 143, 144 ,are chosen to determine deiinite sizes of patties of butter andtheregulator disks 110,113 may be calibrated at theirfupper, side by side, edges, with indications asindicated in Fig. 18, similar to vscale markings, for indicating the adjustment of `the regulator. ln commercial forms of my machine, conforming to the construction illustrated in the drawings, thescale indication 1 represents afsizeot patty et one-thirtieth. of apound, and similarly the scale indications 2, 3 and 4 represent patties of sizes respectivelyone thirty-fifth, one for-l tieth and oneorty-ifth of a' pound. Similar openings may belL provided for-similar definite sizes ofy the severed port-ions of the ceivedona lsuitable dish orfequivalent position below thebottom ofthe casing which y is provided,` with a discharge opening'disposed belowthe discharge opening ot ,the

container. n f t i Upon fully dischargingthe food :in bulk from any container,` the `plunger rod 46 is withdrawn upwardly, freeing itstoe from contact withthe.plunger40funtil clear ot 'thel upperend 7 of the container B, whereupon `the locking bai' 19 is depressed tounlocking position and by means of the handhold 12 `ofthe table 9 is rotated to bring thedesired other container in position be-` low the plungerv mechanism.
